Do not wait until the trade deadline is a week away to start making trades in Fantasy Baseball. The time to make trades is: All the Time. Remember, no trade is too minor, so if someone is asking to trade his third 2nd basemen for your 5th outfielder, take it seriously. There is a very common strategy out there where owners will make a slew of minor trades to acquire the building blocks to make their big trades. Also, never accept the first offer someone gives you, it's probably too good to be true. Finally, check the injury reports, don't trade for Joba Chamberlain today.
I know that you are excited if you own such waiver-wire standouts as Josh Collmenter, Alexi Ogando, and Matt Joyce, but it is time to trade them now. Look for an owner who owns struggling star players such as Dan Uggla, Kevin Youkilis, or Dustin Pedroia and offer one or two of your overachievers in a trade and see if he or she will bite. This is what is classically called as sell high/buy low. It is very common every year that a young player will go on a hot streak when he arrives in the big leagues, but when the rest of the league "gets a book on him" (layman term: adjusts), that player will regress. Conversely, veteran players commonly get better as the season progresses (especially those coming off of injuries from previous seasons), and are worth grabbing for such a low price. If I asked you today 'who will hit 15 home runs first from now until the end of the season, Matt Joyce or Kevin Youkilis?' the answer would commonly come back Kevin Youkilis. Yes, Matt Joyce's stats are significantly better up until this point, but try to take advantage of his hot start and turn it into a more reliable players hot finish.
